Faerie Fire

Cast Time: 1 Action | Duration: 1 Minute
Mats: V | Range: 60 ft | Concentration
Each creature which fails a Dexterity saving
throw and object in a 20-foot cube within range
is outlined in blue, green, or violet light (your
choice). This sheds dim light in a 10-foot radius
for the duration. Attack rolls against affected
creatures or objects have advantage if the
attacker can see it, and the affected creature
or object can't benefit from being invisible.
